Personal Data Server is abbreviated as PDS. The more generic [[Personal Data Store]] is a non-protocol specific label for the concept of people owning their own data.

In [[ATProtocol]], the PDS is where user auth and data is stored. You can use the [[atproto-browser]] to see what is stored for a user, as well as which PDS server they are on.

The [[ATProto Community Wiki]] has a [page of PDS implementations](https://wiki.atprotocol.community/en/wiki/reference/community/implementations/pds-implementations).
